Abstract

Apparatus for splicing the end of a terminating reel to the outer layer of a subsequent reel: a splicing tube is either swingable or reciprocable to move between a waiting position out of contact with the strip to be cut and an operating position where the splicing tube moves transversely to and into contact with the strip and moves the strip to a position where it can be cut by a knife. A knife movable between a waiting position where it will not cut the strip and a cutting position where movement of the splicing tube to the operating position moves the strip to contact the knife for cutting. The knife is supported to be moved between its positions either by swinging or by movement along a guide path. The splicing tube includes a vacuum zone which holds the strip to it, and the splicing tube is rotatable on its axis for maintaining the tension of the strip.

Description

Die Erfindung betrifft eine Einrichtung entsprechend dem Oberbegriff des Patentanspruchs 1. Eine solche Einrichtung ist bekannt aus der EP 462 157 B1. Bei dieser Einrichtung befindet sich ein Trennmesser auf der Splicevorrichtung, die als ein schlanker Hohlzylinder ausgebildet ist und eine Saugzone aufweist. Dabei ist das Trennmesser in einer Nut angeordnet, die in dem Spliceelement ausgebildet ist. Das Trennmesser hat eine eigene Betätigungsvorrichtung, die beim Trennvorgang in Bewegung gesetzt wird. Es ergibt sich dadurch natürlich ein relativ komplizierter Aufbau des Spliceelements mit einer relativ starken Schwächung desselben in beapspruchungsmäßiger Hinsicht, weil die Nut den zylindrischen Mantel unterbricht.The invention relates to a device according to the preamble of claim 1. Such a device is known from EP 462 157 B1. In this device there is a separating knife on the splicing device, which is designed as a slim hollow cylinder and has a suction zone. The cutting knife is arranged in a groove which is formed in the splice element. The cutting knife has its own actuating device, which is set in motion during the cutting process. This naturally results in a relatively complicated structure of the splice element with a relatively strong weakening of the same in terms of claim, because the groove interrupts the cylindrical jacket.

DE 34 40 107 C2 beschreibt eine Einrichtung zum Verbinden des Endes einer ablaufenden Materialbahn mit dem Anfang einer zweiten Materialbahn. Dabei ist ein vom Spliceelement getrennt angeordnetes Messer vorgesehen, das gegen einen gespannten Bahnabschnitt bewegt wird. DE 39 01 854 A1 beschreibt eine ähnliche Vorrichtung, bei welcher die Bahn gegen die Schneide einer Schneidvorrichtung bewegt wird; die Schneidvorrichtung und das Spliceelement sind dabei voneinander getrennt angeordnet.DE 34 40 107 C2 describes a device for connecting the end of a running material web to the start of a second material web. In this case, a knife is provided which is arranged separately from the splice element and is moved against a tensioned web section. DE 39 01 854 A1 describes a similar device in which the web is moved against the cutting edge of a cutting device; the cutting device and the splice element are arranged separately from one another.

Die Aufgabe der Erfindung ist es, eine Einrichtung zur Bahnverbindung anzugeben, die einen relativ einfachen Aufbau hat. Diese Aufgabe wird erfindungsgemäß durch die Merkmale des kennzeichnenden Teils des Patentanspruchs 1 gelöst.The object of the invention is to provide a device for rail connection, which has a relatively simple structure. This object is achieved by the features of the characterizing part of patent claim 1.

Durch die erfindungsgemäße Ausbildung der Einrichtung ist das Spliceelement sehr einfach aufzubauen, indem es im wesentlichen aus einem zylindrischen Rohr besteht, das in einem gewissen Bereich an seinem Mantel eine Saugzone erhalten hat. Es ist sehr biegesteif und kann daher mit relativ kleinem Durchmesser ausgeführt werden, was auch eine erhebliche Gewichtsersparung mit sich führt. Die Betätigungseinrichtung des Trennmessers kann ebenfalls sehr robust, solide und einfach ausgeführt werden. Bei einer Reparatur müssen keine umständlichen Vorbereitungen getroffen werden, und das Auswechseln der Trennschneide kann relativ einfach und schnell erfolgen.Due to the design of the device according to the invention, the splice element is very easy to assemble, in that it essentially consists of a cylindrical tube which has a suction zone on its jacket in a certain area. It is very resistant to bending and can therefore be designed with a relatively small diameter, which also results in considerable weight savings. The actuating device of the cutting knife can also be made very robust, solid and simple. No laborious preparations need to be made for a repair, and the cutting blade can be replaced relatively easily and quickly.

Nachfolgend wird die Erfindung anhand der Figuren der Zeichnung erläutert, welche jeweils eine Seitenansicht, zum Teil ausschnittweise, der verschiedenen Erfindungsvarianten in prinzipieller Darstellung wiedergeben.The invention is explained below with reference to the figures of the drawing, which each show a side view, partly in part, of the different variants of the invention in a basic representation.

Der Tambour ist mit zwei Kreisen 1 und 1' strichpunktiert dargestellt, wobei der Tambour 1' den größtmöglichen Umfang hat. Die vom alten, jetzt ruhig gestellten, Bahnwickel 9 abgelaufene Bahn ist mit T bezeichnet. Sie wird durch das Spliceelement 2 aus der ausgezogen dargestellten Stellung in die strichpunktierte Stellung bei der Schwenkbewegung desselben mitgenommen. Diese Schwenkbewegung wird durch Schwenkarme 3 ermöglicht, die an dem Ständer 12 befestigt sind, der auch die erste Umlenkwalze 5 für die Bahn trägt. Weitere Umlenkwalzen 21 und 22 leiten die Bahn weiter. Die Trennvorrichtung ist mit 10 angegeben, wobei eine Schneide 11 und ein Betätigungsantrieb 15 z.B. in Form eines hydraulischen Hubwerkes vorgesehen ist. In der Figur ist die Trennvorrichtung in der Arbeitsposition gezeichnet, in welcher die Durchtrennung der Bahn bei ruhender Schneide bzw. Messervorrichtung durch die gespannte Bahn selbst erfolgt. Dies ist auch die eine Arbeitsposition des Spliceelements 2, das als rohrförmiger Zylinder angedeutet ist und eine Saugzone 4 in Form eines durchlöcherten Mantels aufweist. Beim Saugvorgang wird das Innere des Rohres unter Unterdruck gesetzt. Der zugehörige Unterdruckanschluß ist hier nicht dargestellt. Es ist eine weitere Arbeitsposition angegeben, bei welcher das Spliceelement - gestrichelt ausgeführt - an dem Bahnwickel 1 kleineren Durchmessers anliegt. Die oberste Position des Spliceelements ist die Warteposition, in welcher dieses in seiner Ausgangsstellung verharrt. Durch Herabschwenken des Spliceelements aus dieser Position in die untere Arbeitsposition entlang dem Bogen S wird die Bahn eingefangen, indem sie sich an die Saugzone des Spliceelements anlegt. Dann kann der Trennvorgang durch das Messer 11 erfolgen, wobei dieses jedoch schon vorher in diese Arbeitsposition gebracht werden muß, in welcher es dann einige Zeit bis zum Trennvorgang verharrt.The drum is shown with two circles 1 and 1 'in dash-dot lines, the drum 1' having the greatest possible extent. The web that has run off the old, now immobilized, web winding 9 is designated by T. It is carried along by the splice element 2 from the position shown in the solid line to the dash-dot position during the pivoting movement. This pivoting movement is made possible by pivoting arms 3, which are fastened to the stand 12, which also carries the first deflecting roller 5 for the web. Further deflecting rollers 21 and 22 forward the web. The separating device is indicated at 10, a cutting edge 11 and an actuating drive 15 e.g. is provided in the form of a hydraulic hoist. In the figure, the separating device is drawn in the working position in which the web is severed when the cutting edge or knife device is stationary by the tensioned web itself. This is also the one working position of the splice element 2, which is indicated as a tubular cylinder and has a suction zone 4 in the form of a perforated jacket. During the suction process, the inside of the tube is placed under negative pressure. The associated vacuum connection is not shown here. A further working position is indicated in which the splice element - shown in dashed lines - bears against the web winding 1 of smaller diameter. The uppermost position of the splice element is the waiting position in which it remains in its starting position. By swiveling the splice element down from this position into the lower working position along the arc S, the web is caught by contacting the suction zone of the splice element. Then the cutting process can be carried out by the knife 11, but this must be brought into this working position beforehand, in which it then remains for some time until the cutting process.

Beim Hochschwenken des Spliceelements 2 in die weitere Arbeitsposition, in welcher der Splicevorgang stattfindet, kann vorzugsweise das Spliceelement um seine eigene Achse durch einen entsprechenden Antrieb verdreht werden, so daß die Bahn während dieses Vorganges strammgehalten bleibt. Das Spliceelement wird in die obere, ausgezogen dargestellte End- oder Warteposition zurückgeschwenkt, dann der neue Tambour durch eine bekannte, hier aber nicht dargestellte Transportvorrichtung an die Stelle des alten Bahnwickels 9 in die übliche Halterung eingelegt und dann der Splicevorgang durch Anlegen des Spliceelements 2 an den Umfang des neuen Tambours durchgeführt. Für diesen Zweck weist die letzte Windung des neuen Tambours natürlich an dieser Splicestelle einen Klebeauftrag, z.B. in Form eines doppelseitigen Klebestreifens, auf. Die Bahn T' verläuft dann im wesentlichen in horizontaler Richtung zur ersten Umlenkrolle 5 hin.When the splice element 2 is swiveled up into the further working position in which the splicing process takes place, the splice element can preferably be rotated about its own axis by a corresponding drive, so that the web remains taut during this process. The splice element is pivoted back into the upper, drawn-out end or waiting position, then the new drum is inserted into the usual holder in place of the old web winding 9 by a known, but not shown, transport device, and then the splicing process by applying the splice element 2 carried out the scope of the new drum. For this purpose, the last turn of the new drum naturally has an adhesive application at this splice point, e.g. in the form of a double-sided adhesive tape. The web T 'then runs essentially in the horizontal direction towards the first deflection roller 5.

Man erkennt, daß die Einrichtung relativ einfach aufgebaut ist, und daß auch der hier angegebene maximale Schwenkbereich der Schwenkarme 3 durch eine entsprechende Hubvorrichtung 14 - z.B. hydraulischer Art - ohne weiteres durchführbar ist. Eine ähnliche Anordnung ergibt sich bei umgekehrten Bahnablauf von Tambour und altem Bahnwickel im Fall einer entgegengesetzten Wickelrichtung derselben.It can be seen that the device is of relatively simple construction and that the maximum swivel range of the swivel arms 3 specified here can also be easily carried out by a corresponding lifting device 14, for example of a hydraulic type. A similar arrangement results with the reverse web of the drum and the old web winding in the case of an opposite winding direction.

Die in Figur 2 dargestellte erfindungsgemäße Anordnung entspricht im Prinzip derjenigen von Figur 1. Im wesentlichen geändert worden ist nur die Messervorrichtung. Zur Lagerung der Messervorrichtung sind hier jeweils ein Ständer 24 neben dem Tambour vorgesehen, die sich entfernt von dem Abrollgestell 41 mit der Lagerung 36 des jeweiligen Tambours befinden. Die Messervorrichtung besteht aus dem Messer 11, einem langgestreckten, stab- oder balkenförmigen Träger 31 und Seitenträgern 25, die den langgestreckten Träger 31 halten. Der Träger 31 erstreckt sich längs des Tambours ebenso wie das Messer 11'. Die Seitenträger 25 sind hier mittels Rollen 29 und 30 in den Führungsbahnen 27 der Ständer 24 geführt. Der Antrieb erfolgt über eine Kette 34 und eines der Kettenräder 32 und 33 über einen hier nicht dargestellten Antriebsmotor, z.B. einen Elektromotor. Das obere Ende der Führungsbahn 27 und dementsprechend die Schneidposition des Messers 11' befindet sich oberhalb der durch die Tambourachse verlaufenden Horizontalebene H. Auch hier wird der Schneidvorgang durch das Herabschwenken der Splicevorrichtung 2 in die hier angegebene untere Position im wesentlichen allein durch die Bahnspannung bewirkt. Weitere Einzelheiten der Hilfseinrichtungen zur Bewegung des Tambours sind hier ebenfalls in Figur 1 nicht dargestellt. Zu erwähnen ist noch, daß das Abrollgestell 41 auf einer Grundplatte 42 des Fundaments ruht.The arrangement according to the invention shown in FIG. 2 corresponds in principle to that of FIG. 1. Only the knife device has essentially been changed. To support the knife device, a stand 24 is provided here next to the drum, which is located at a distance from the unwind frame 41 with the bearing 36 of the respective drum. The knife device consists of the knife 11, an elongated, rod-shaped or beam-shaped carrier 31 and side carriers 25 which hold the elongated carrier 31. The carrier 31 extends along the drum just like the knife 11 '. The side supports 25 are guided here by means of rollers 29 and 30 in the guideways 27 of the stand 24. The drive takes place via a chain 34 and one of the chain wheels 32 and 33 via a drive motor, not shown here, e.g. an electric motor. The upper end of the guideway 27 and accordingly the cutting position of the knife 11 'is located above the horizontal plane H running through the drum axis. Here too, the cutting process is brought about by pivoting the splicing device 2 down into the lower position indicated here, essentially solely by the web tension. Further details of the auxiliary devices for moving the drum are also not shown in FIG. 1 here. It should also be mentioned that the rolling frame 41 rests on a base plate 42 of the foundation.

In Figur 3 ist eine ähnliche Antriebseinrichtung für die Messervorrichtung dargestellt, wobei auch hier eine Kette, ein Seil oder auch ein Zahnriemen 40 benutzt werden kann. Der Antrieb erfolgt hier jedoch über einen hydraulischen oder pneumatischen Stellzylinder 39 und einen Hebel 38, der jeweils an den Seitenträgern 25 der Messervorrichtung befestigt ist.FIG. 3 shows a similar drive device for the knife device, wherein a chain, a rope or a toothed belt 40 can also be used here. Here, however, the drive takes place via a hydraulic or pneumatic actuating cylinder 39 and a lever 38 which is fastened in each case to the side supports 25 of the knife device.

In den Figuren 2 und 3 ist mit Winkel a der günstige Bereich zum Anbringen des Klebestreifens für den Splicevorgang angedeutet. Im wesentlichen verlaufen die Führungsbahnen 27, 27' und auch die Ständer 24 vertikal, vorzugsweise höchstens 30 von der Vertikalen abweichend. Dadurch wird eine sehr raumsparende Anordnung erzielt, was bei beengten Raumverhältnissen z.B. durch die Art der Ausbildung der Abrollständer günstig ist. Daher befinden sich auch in günstiger Weise die Ständer 24 - in Richtung quer zum Tambour 1, 1' - entfernt von den Rollenständern 41.In FIGS. 2 and 3, the favorable area for attaching the adhesive strip for the splicing process is indicated by angle a. The guideways 27, 27 'and also the uprights 24 essentially run vertically, preferably at most 30 deviating from the vertical. This results in a very space-saving arrangement, which is possible in confined spaces e.g. is favorable due to the type of training of the unwind stand. Therefore, the stands 24 are also located in a favorable manner - in the direction transverse to the drum 1, 1 '- away from the roller stands 41.

In Figur 4 ist eine ähnliche Einrichtung bezüglich der Messervorrichtung dargestellt wie in Figur 2. Hier ist jedoch ein anderer Antriebs des Spliceelements 2 vorgesehen. Und zwar wird hier über einen Halter 54 eine von einem Gleitschlitten 53 geführte Antriebsstange 50 von der Kolbenstange 52 eines hydraulischen oder pneumatischen Hubelements 51 betätigt. Die Führungsbahn des Gleitschuhs 53 ist mit 54 angedeutet. Das ganze wird von einer Konsole 56 mit Aufsatz 57 getragen. Diese ruht auf einem Ständer 12', der auch die erste Umlenkrolle 5' für die Bahn aufnimmt.FIG. 4 shows a similar device with regard to the knife device as in FIG. 2. Here, however, a different drive of the splice element 2 is provided. Specifically, a drive rod 50 guided by a slide 53 is actuated by a piston 54 of a hydraulic or pneumatic lifting element 51 via a holder 54. The guideway of the slide shoe 53 is indicated by 54. The whole is carried by a console 56 with an attachment 57. This rests on a stand 12 'which also receives the first deflection roller 5' for the web.

In Figur 5 ist der Antrieb der Messervorrichtung gemäß Figur 2 wieder auf eine etwas andere Weise variiert. Die Seitenträger 25' für den balkenförmigen Messerträger 31 - hier als Rohr ausgebildet - gleiten auf Rollen 29' und 30' und werden über eine Verbindungslasche 67 von einem Führungswagen 60 angetrieben, der mittels Rollen 61 und 62 in den Führungsbahnen 27' des Ständers 59 an einer Kette 34' bewegt wird. Diese wird wiederum über ein hier nicht mehr erkennbares Kettenrad, das dem Kettenrad 33 entspricht, von einem Motor, z.B. einem Elektromotor, angetrieben. Der Ständer 59 erhält noch besondere Stabilität durch eine Versteifungsrippe 65. Die Seitenträger 25' weisen jeweils einen Fortsatz 66 auf, an welchem der Messerbalken 31 befestigt ist. Der Ständer 59 kann zu seinen beiden Seiten die Führungsbahnen 27' im wesentlichen bis zu der hier dargestellten oberen Position des Führungswagens 60 aufweisen, so daß jeweils zwei Rollenpaare 64 und 62 in diese Führungsbahnen eingreifen, so daß der Führungswagen 60 recht gut geführt ist.In FIG. 5 the drive of the knife device according to FIG. 2 is again varied in a somewhat different way. The side supports 25 'for the bar-shaped knife support 31 - here in the form of a tube - slide on rollers 29' and 30 'and are driven via a connecting bracket 67 by a guide carriage 60 which engages in the guide tracks 27' of the stand 59 by means of rollers 61 and 62 a chain 34 'is moved. This is in turn driven by a motor, e.g. via a chain wheel no longer recognizable here, which corresponds to the chain wheel 33. an electric motor. The stand 59 is also given particular stability by a stiffening rib 65. The side supports 25 'each have an extension 66 to which the cutter bar 31 is fastened. The stand 59 can have on both sides of the guideways 27 'substantially up to the upper position of the guide carriage 60 shown here, so that two pairs of rollers 64 and 62 each engage in these guideways, so that the guide carriage 60 is guided quite well.

Die in den Figuren 2-5 dargestellte Messerbetätigungseinrichtung hat den Vorteil, daß Hindernisse von dem Messer umgangen werden können, wobei in diesen Fällen das Hindernis praktisch der alte Bahnwickel 9 ist. Durch die Führungsbahnen kann eine recht günstige Schneidposition und kommt auf diese Weise sehr nahe an den oberen Umfangsbereich des Bahnwickels 9 heran, wenn es in seine Schneidposition gelangt ist.The knife actuation device shown in FIGS. 2-5 has the advantage that obstacles can be avoided by the knife, in which case the obstacle is practically the old web winding 9. Due to the guideways, a very favorable cutting position can be achieved and in this way comes very close to the upper peripheral region of the web winding 9 when it has reached its cutting position.
